VEHICLE WHEEL.

Original application filed. July 3, 1924,

late the manufacture of an all-metal wheel while, at the same time,providing a secure and rigid crmstruction.

Other and incidental objects will appear hereinafter.

1n the accon'ipanying drawings:

Figure 1 is a fragmentary sectional View of a wheel embodying thepresent improvements,

Figure 2 is a fragmentary perspective view of the wheel hub, and

Figure 3-is a detail sectional View on the line 3-3 of Figure 1, lookingin the direction indicated by the arrows.

The wheel of the present invention is constructed entirely of metal andembodies a hub from which radiate a plurality of tubular spokes 11.Supported by the spokes in concentric relation to the hub is achannel-shaped felly having-a bottom wall 12, one side wall 13, and anopposite side wall 14. The bottom wall 12 of the felly is apertured toreceive the outer'ends of the spokes which, as shown in Figure 1, areturned down against the adjacent face of said wall for rigidlyconnecting the folly with the spokes. The side wall 13 of the felly isprovided with a lateral inclined flange 15 While the side wall. 14 isformed with an inturned flange 16 and slidabie across the latter flangeto coact with the flange 15, is a rim 17 secured by rim clamps 18. Aconventional. tire 19 has been illustrated in connection with the rim.

Coming now more particularly to the subject of the present improvements,the hub Serial No. 724,134. Divided and this application filed October23, 1924. Serial No. 745,447.

10 is, as particularly shown in Figure 2, provided with a plurality ofradial slots 20 and 4 formed in the opposite side faces of the hub areannular channels 21. The spokes 11 are rolled or otherwise shaped attheir inner ends to form flattened terminals 22 and, as shown in Figure3, these terminals are inserted in the slots 20 of the hub and are upsetat their side edges to form locking ribs 23 lying within the channels21. vInitially, the terminals of the spokes are of'a width to project atthe side faces of the hub so that the side edges of the terminals maythus be readily hammered for compressing the terminals within the slots20 as Well as producing the locking ribs 23. In thus upsetting theprojecting margins of the spoke terminals 22 in the channels 21 of thehub, said terminals are caused to bind in the slots 20 for tightlysecuring the spokes against radial movement while the ribs 23 will, ofcourse. rigidly lock the spokes against lateral displacement. A secureand rigid connection between the spokes and the hub is thus providedwhile, at the same time, the construction is such as to facilitate themanufacture of the wheel. 7

Having thus described the invention, what I claim is:

The combination with a hub having radial slots and annular channels inopposite sides forming innerand outer stop shoulders. of tubular spokeshaving their inner ends flattened'and fitted within the radial slots ofthe hub. and having opposite side portions upset to lie within thechannels and overlap the walls of the radial slots and abut the innerand outer stop shoulders. whereby to prevent any longitudinal andlateral movement of the spokes in their rcspectiveradial slots.

In testimony whereof I afiix my signaturev FREDERICK L. MINNICK. a 8.
